It is an object of the present invention to provide a highly reliable optical sensor and a production process of the same, the optical sensor being excellent in the characteristic of blocking infrared radiation and capable of being manufactured at a low cost without an increase in the number of steps carried out in the assembly of electronic apparatus. The present invention includes: a substrate 1 having an electrode 3; a photodetector 2 electrically connected to the electrode 3; and a light-transmissive resin encapsulating portion 11 for encapsulating the photodetector 2 on the substrate 1, the optical sensor further including an infrared-blocking layer either inside the light-transmissive resin encapsulating portion 11 or on an outer surface of the light-transmissive resin encapsulating portion 11 for blocking infrared radiation from the outside from reaching the photodetector.
An optical sensor comprising:
An optical sensor comprising:
A process of producing an optical sensor, comprising the steps of:
A process of producing an optical sensor, comprising the steps of:
A light-transmissive resin composition both for an optical sensor filter and for encapsulating a photodetector of an optical sensor, the light-transmissive resin composition having an infrared radiation blockage function provided by addition of a plurality of phthalocyanine dyes as infrared-absorbing substances to a light-transmissive resin.
